Effect of PGR on Growth and Yield of Cucumber under Shadenet Condition

Cucumber (Cucumis sativus L.) is a widely cultivated plant, belonging to the family Cucurbitaceae and having a chromosome number, 2n =14. In botanical terms, the cucumber is classified as a pepo, a type of botanical berry with a hard outer rind and no internal divisions. PGR such as GA3, NAA and Ethrel include many aspects of plant growth, development and flowering and yield. They are organic substances when they are used in low concentration to change the plant growth usually by stimulating part of the natural growth regulatory system. Now a day farmers are using PGR on large scale in vegetables specially cucurbits. It play vital role in growth, development, flowering, sex expression and increase in yield. Farmer are cultivating cucumber hybrids under shade net condition but they are facing many problems related to the production technology related to flowering and due to less adoption of plant nutrition, growth regulators under shade net cultivation which leads to poor growth and yield of cucumber. Therefore, keeping all the point in view the present investigation entitled "Effect of PGR on cucumber under shade Net condition" was undertaken.
